We would love to find ways to reduce carbon dioxide as a threat to our climate with an ever-decreasing timeline for accomplishing that task. University of Illinois at Chicago and Massachusetts Institute of Technology (MIT) have made inroads into creating a carbon dioxide battery that uses CO2 as an energy storage component. Amin Salehi-Khojin, associate professor of mechanical and industrial engineering at UIC’s College of Engineering, explains, “Lithium-carbon dioxide batteries have been attractive for a long time, but in practice, we have been unable to get one that is truly efficient until now.” A 7X Battery The incentive to use CO2 comes from lithium-carbon dioxide batteries having a specific energy density more than seven times greater than conventional lithium-ion cells. …
